2007年建成的北京正负电子对撞机（BEPCII）升级改造项目的直线加速器（Linac）为存储环提供1.89GeV的电子和正电子。 BEPCII直线加速器决定对聚束系统进行更新，并采用双束加速技术来提高光束质量和注入速率，作为其第二个更新阶段。该项目将使用两个分谐波聚束器：一个工作频率为 142.8MHz，另一个工作频率为 571.2MHz。每个分谐波聚束器由聚束腔、电源、LLRF系统和其他相关子系统组成。本文主要描述分谐波聚束系统（SHB）的 LLRF 系统。
The linear accelerator (Linac) completed in 2007 for the upgrading project of the Beijing Electron Positron Collider (BEPCII) provides 1.89GeV electrons and positrons for the storage rings. BEPCII Linac decides to update the bunching system and adopts two bunches acceleration technology to enhance beam quality and injection rate as its second update phase. Two subharmonic bunchers will be used in this project: one operates at 142.8MHz and the other operates at 571.2MHz. Each subharmonic buncher consists of the bunching cavity, power source, LLRF system and other related subsystems. This paper mainly describes the LLRF systems for the subharmonic buncher systems (SHB).
